The Dark Side of Isaac Newton

Following completion of his natural science degree at Cambridge specialising in the history and Philosophy of Science, Nick Kollerstrom worked for the Medical Research Council's Air Pollution Unit. This resulted in his first book _Lead on the Brain_, an investigation into lead pollution from petrol, and this was promoted by the Green Party to raise awareness. While living in Guildford, he worked as a secondary school maths teacher for five years. He worked in the local Green Party and it was very successful; in 1989 they secured 22% of the vote for West Surrey Green Party in the Euro-election.

While studying at Emerson College and working on a bio-dynamic farm he became interested in planting by the Moon and lunar influences. He collaborated with Simon Best producing Britain's lunar gardening Calendar from 1980 which has now been running for 35 years, _Planting and Gardening by the Moon_. For a while he was the BBC's lunar gardening correspondent.

He has authored many books exploring a wide variety of subjects, including _The Unnecessary War_ (1988), _Newton's Forgotten Lunar Theory_ (2000) _Crop Circles, the Hidden Form_ (2002), _Terror on the Tube_ (2009), and _Venus, the Path of Beauty_ (2017).
